Since 2013, 96 ring spinning machines from the textile machinery manufacturer Zinser, featuring a total of more than 136,000 spindles, have been in use at the state-run Chinese Xianyang Textiles Group in conjunction with the Autoconer package winding machine from Schlafhorst.

According to the company, the new ZinserRing 71ring spinning system has far exceeded its expectations. According to Xianyang Textiles, the ZinserRing 71 is the perfect solution for the latest requirements in the Asian textile industry. Due to the increasingly difficult issue of workforce availability, spinning mills must make themselves less and less reliant on personnel. Delivery of any desired yarn at a guaranteed quality and at an unrivalled price-performance ratio is what companies want from their modern machinery.

"The markets are constantly changing", says Yang Renhong, Head of Spinning Department at Xianyang Textiles. "There are fluctuations in the availability of raw materials and in the level of demand for the various yarns. The ZinserRing 71 puts us in a position where we can ideally meet changing market requirements, as we want to continue to grow regardless of fluctuations in the market."

Xianyang Textiles Group

Xianyang Textiles Group was originally founded under a different name back in 1952, before relocating to Xianyang Emerging Textile Industrial Park in 2012. The industrial park is an important textile production centre along the new Chinese Silk Road. With around 5,000 employees and a production capacity of 400,000 spindles, Xianyang Textiles is one of the largest textile companies in north-west China and boasts an annual production of 50,000 tonnes of yarn.

The company processes cotton, manmade fibres and their blends to create high-grade yarns. Xianyang Textiles operates its own weaving mills and dye shops, thereby covering a broad scope of the textile net product chain. Part of the production is exported to over 50 countries, with a particular focus on Europe, North America, Japan, Korea, South-East Asia, and Africa.

Stable precision technology

Upon commissioning the ring spinning machines from Zinser, Xianyang Textiles expected to achieve a significant reduction in spinning costs. This expectation was met by the ZinserRing 71. As well as providing particularly high levels of performance, it also ensures maximum efficiency thanks to the precision of the assemblies, according to the manufacturer.

The ZinserRing 71 enabled Xianyang Textiles to record a drop in power consumption. With its energy-saving tangential belt drive, its precision-mounted high-speed spindles featuring a low power requirement and its energy-efficient motors, the economical ZinserRing 71 produces more yarn using less electricity.

The stable and reliable design of the ZinserRing 71 also reportedly enabled Xianyang Textiles to increase the spinning speeds without the risk of yarn breaks. The integrated OptiStep software is designed to ensure that the start, coast-down and operational spinning speeds are optimally attuned to the technological spinning limit.

Consistent quality

The drafting system of the ZinserRing 71 features mechanical weighting arms that are designed to guarantee consistent pressure at all spinning positions. This reliability leads to yarn values that are consistent at all times, enabling Xianyang Textiles to achieve top quality with maximum process reliability and significantly reduced maintenance input, the company reports.

CoWeMat

With its renowned process reliability and dependable operation, the CoWeMat technology for doffing automation is designed to reduce personnel costs and increases efficiency. Fast, reliable automatic bobbin changing on the ZinserRing 71 by the CoWeMat makes it possible to utilise the production capacity to optimum effect, as it performs the work arising at intervals without the need for staff, the company explains.

"In contrast to our previous installations, there are no bottlenecks, waiting times or downtimes," says Yang Renhong. "This ensures the highly efficient operation of the ring spinning system at all times. In addition, the CoWeMat has reduced the maintenance input during the doffing process to a minimum, providing a level of reliability that has enabled us to reduce our personnel costs."
